RAILWAY-BED CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 762,207, dated June 7,1904:.

Application filed December 24, 1903. Serial No. 186,472. (No model.)

To all whom it may concern.-

' Be it known that I, ROBERT E. SMITH, a citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Railway Bed Construction, of which the followingis a specification containing a full, clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.

My invention relates to railway-beds, my object being to reduce theamount of wood required for ties in railway-bed construction and to givethe bed increased strength and durability.

My improved railway bed construction comprises the combination, with asuitable grade, of two parallel rows of ties laid end to end, dowel-pinsconnecting the ties, anchors embedded in the grade below and between therails, tie-rods connecting the rails, anchorrods connecting the ends ofthe tie-rods inside of the rails to the anchors, and anchor-platesconnected to the tie-rods outside of the rails and embedded in thegrade.

Figure 1 is a cross-section of a railway-bed construction embodying theprinciples of my invention. Fig. 2 is a top plan, parts being shown insection and other parts being broken away. Fig. 3 is a sectional Viewshowing how the ties are connected by dowel-pins.

Referring to the drawings in detail, the wooden ties 4: are laid end toend in two parallel rows upon the grade 5, the ends of said ties beingconnected by the dowel-pins 6. The rails 7 are mounted upon the ties 4and secured to said ties by the spikes 8. Wells are dug in the grade 5between and, below the rails. The anchors 9 are placed in said wells,and the wells are filled around the anchors with cement or concrete 10.The anchors, as shown, are sections of corrugated tubes, this being avery favorable form of anchor, be-' cause it will sit firmly in the bedof cement; but other forms may be used. Openings 9 are formed in thewall of the anchor 9, and cement passes through said openings to fillthe tube. The tie-rods 11 have their ends inserted through the rails 7,and the anchorrods 12 and 13 extend downwardly and in wardly from theends of the tie-rods inside of the rails and have hooks 14c to engage inthe anchor 9, said anchor-rods being connected to the anchors,preferably before the cement is placed, and after the cement is placedthe Wells are filled and the grade finished between the rails. Theanchor-plates 15 are placed in position outside of the rails with theends of the tie-rods 11 extending through said anchorplates, saidanchor-plates extending downwardly and outwardly outside of the rails,and when the grade is finished said plates are embedded in the grade.The nuts 16 are screw-threaded upon the extreme outer ends of thetie-rods and hold the parts firmly together.

A great saving in ties is effected by laying the ties end to end. Thesystem of anchorage efi'ectually prevents the ties and rails from movinglaterally upon the grade.

I claim 1. A railway-bed construction, comprising the combination withasuitable grade, of two parallel rows of ties laid end to end; dowelpinsconnecting the ties; anchors embedded in the grade below and between therails; tierods connecting the rails; anchor-rods connecting the ends ofthe tie-rods inside of the rails to the anchors; anchor-plates connectedto the tie-rods outside of the rails and embedded in the grade,substantially as specified.

2. In a railway-bed construction, asuitable grade, ties mounted end toend upon the grade, rails mounted upon the ties, anchors embedded in thegrade below and between the rails, and anchor-rods extending upwardlyand outwardly from the anchors to the rails, thereby connecting therails to the grade and thereby connecting the rails together through theanchors, substantially as specified.

3. In a railway-bed construction, a suitable grade; ties laid end to endupon the grade; rails upon the ties; tie-rods connecting the rails; andmeans of anchoring the rails to the grade, substantially as specified.

4. In a railway-bed construction, a suitable grade; ties laid end to endupon the grade; rails upon the ties; anchors embedded in the grade;tie-rods connecting the rails; and anoutside of the rails and embeddedin the grade, 10 substantially as specified.

In testimony whereof I have signed my name to this specification inpresence of two subscribing Witnesses.
